This is an odd one. I'm doing billing for an LMT who says he's not credentialed in Medicare. This provider has a patient with Medicare primary and Blue Cross secondary ins. This provider told me to submit claims to Medicare, then simply bill the secondary insurance (Blue Cross) stating Medicare has not paid anything on this claim. This doesn't sound right to me, with no Medicare EOB, they'll be no documentation proving I sent anything to Medicare, and I'm even thinking there may be a legal issue with this. Any suggestions?
